  • the application 1051 creates the print settings (the print ticket) for the page of which print settings to be changed. At that creation, the application 1051 creates the print settings (the print ticket) for a whole including not only the functions in the page scope indicating the values of the print settings to be changed hut also the functions in the document scope and the job scope. Then, in S 505 , the application 1051 designates the created print settings (print ticket) with the API of the OS 1053 that changes the page setting.
  • the API used here is MXDC_ESCAPE.
  • the application 1051 draws the page to be printed.
  • the application 1051 only draws the page as normal when the print settings are not changed in the middle of the printing.
  • the application 1051 determines whether the page drawn in S 506 is the last page of the job. If the drawn page is not the last page, the process returns to S 503 . The application 1051 repeats S 503 to S 506 to print a plurality of pages included in the job. In S 508 , the application 1051 declares to the OS 1053 that the application 1051 terminates the printing, using API (EndDoc).
  • FIG. 8 illustrates APIs in order in which the GDI application 301 invokes when performing printing along the flowchart of FIG. 5 .
  • the GDI application 301 is stored on the auxiliary memory device 105 of the computer, and is read by the RAM 1022 and executed by the CPU 101 .
  • the GDI application 301 invokes the API (StartDoc) for starting printing to generate a print ticket for a job using the DEVMODE-print ticket conversion module 3081 ( 5101 ).
  • ResetDC There are two APIs for switching the settings for each page, an API ( 5102 ) referred to as ResetDC and an API ( 5103 ) referred to as MXDC_ESCAPE.
  • the ResetDC generates a print ticket for a page using the DEVMODE-print ticket conversion module 3081 .
  • the MXDC_ESCAPE is used when the GDI application 301 generates a print ticket by itself for direct insertion.
  • the GDI application 301 uses the DEVMODE structure to create a print ticket.
  • the GDI application 301 uses the MXDC_ESCAPE ( 5103 )
  • the GDI application 301 generates the print ticket by itself.
  • the GDI application 301 uses the MXDC_ESCAPE as the API used to switch (change) the setting for each page instead of the ResetDC. This is because only a print ticket only including the functions in the page scope can be generated with the DEVMODE-print ticket conversion module 3081 when the ResetDC ( 5102 ) is used.
  • FIG. 9 illustrates APIs in order in which the XPS application 302 invokes when performing printing along the flowchart of FIG. 5 using an API group referred to as Direct2D.
  • the XPS application 302 is stored on the auxiliary memory device 105 of the computer, and is read by the RAM 1022 and executed by the CPU 101 .
  • the XPS application 302 designates the print ticket 304 for the whole job, which the XPS application 302 creates by itself, with an API referred to as CreateDocumentPackage to apply the print settings for the whole job ( 5201 ). Similarly, the XPS application 302 uses an API referred to as AddPage to designate the print ticket 304 for the whole job, which the XPS application 302 creates by itself, to switch the print settings for each page.
  • the renderer filter 315 receives the XPS spool file 306 from the filter pipeline manager 312 .
  • the renderer filter 315 obtains the print ticket for the whole job from the XPS spool file 306 .
  • the renderer filter 315 interprets the print ticket for the whole job and generates a PJL that is a printer job language for the whole print job.
  • the renderer filter 315 stores the setting values of the print setting items corresponding to a plurality of functions in the job scope and the document scope of the print ticket for the whole job on the storage area (for example, the RAM 1022 ).
  • the renderer filter 315 checks whether there is a print ticket for the page that is currently to be processed among the pages in the print job in the XPS spool file 306 . If there is the print ticket 304 for the page that is currently to be processed, the process goes to S 606 . If there is not the print ticket for the page, the process goes to S 609 .
  • the renderer filter 315 compares the print setting items corresponding to the functions belonging to the job scope and the document scope included in the print ticket for each page with the setting values of the print setting items held in S 604 , respectively. If there is a difference between the setting values of any of the print setting items, the process goes to S 607 . If there is not a difference between the setting values, the process goes to S 608 .
  • the fact that the process goes to S 607 means that at least a print setting value corresponding to any of functions belonging to the job scope or the document scope is changed in one of the pages included in the job.
  • the renderer filter 315 puts a control code (a PJL command) as a separator to make the printer 1042 recognize that the job or the document is switched. Issuing such a control code can generate another PJL for control the printing, which has at least a different print setting value corresponding to any of functions belonging to the job scope or the document scope from the previous print setting value in a page in the job. Note that, in order to change a setting value corresponding to a function belonging to the page scope, a PJL command about the page to be processed is issued as normal, or the PDT drawing data is switched, instead of putting a control code as a separator.
  • a control code a PJL command
  • the renderer filter 315 further generates a PJL that is different from the PJL generated in S 603 and according to the setting values corresponding to the functions in the job scope and the document scope included in the print ticket for the page to be processed.
  • the renderer filter 315 generates a PJL of the page to be processed from the print ticket for that page.
  • the renderer filter 315 obtains FixedPage from the XPS spool file 306 to generate a PDL of the page to be processed.
  • the renderer filter 315 determines whether the last page is processed. If there is a next page, the process returns to S 605 and the renderer filter 315 repeats S 605 to S 609 . If there is not a next page, in other words, if the renderer filter 315 recognizes that the process of the last page is completed, the renderer filter 315 transmits the XPS spool file 306 to the next filter in S 611 and ends the process.
  • the present exemplary embodiment enables switching (changing) a function belonging to scopes other than the page scope, such as stapling, punching, or two-sided printing, at a page in the middle of the job when the V4 printer driver is used.
  • a setting value included in the print ticket for a page sometimes conflicts with a setting value included in the print ticket for another page among a plurality of pages in a job in the first exemplary embodiment.
  • a print ticket for the fourth page and a print ticket for the sixth page in a job there are a print ticket for the fourth page and a print ticket for the sixth page in a job, and a setting value for turning the staple setting ON is described in the print ticket for the fourth page and a setting value for turning the punch setting ON is described in the print ticket for the sixth page.
  • the printer 1042 is a model that does not enable the stapling function and the punching function simultaneously, it may be impossible to reflect the setting for the sixth page in the output result.
  • the renderer filter 315 also checks the setting value of another function likely to conflict with the function of which setting value is changed when comparing the changed setting value with the previously held content in S 606 .
  • the renderer filter 315 compares the priorities of the conflicting functions.
  • the process in S 607 is skipped.
  • the order of priorities of the functions is previously defined.
  • Such a process enables properly changing the print settings in a page in the middle of a job according to the priority order among the functions.
  • FIG. 7 illustrates a print ticket that defines two-sided print settings, which are normally defined as a function belonging to the document scope, as a function belonging to the page scope.
  • the print ticket defines the two-sided print settings as a function belonging to the page scope in an extended region that the printer driver uniquely defines.
  • the name of the function includes a prefix “Page”.
  • Such definition makes it possible to treat the two-sided print settings as a function for a page. This enables the GDI application 301 to switch the print settings without using the MXDC_ESCAPE ( 5103 ).
